In this study, we validated the debris model included in the tsunami simulator T-STOC by the hydraulic experiments that a container landed after drifting under the tsunami backwash. We measured the friction coefficient on the container model bottom and ground under wet and dry condition, and the drag coefficient of the drifting container model. We investigated the effect of each coefficient on the calculation of the acting force, drifting velocity and position. As a result, it shown that the calculated drifting position using the friction coefficient measured under the wet conditions was consistent with experimental results. Although the measured drag coefficient was slightly larger than the general drag coefficient of rectangular solid, the drifting speed and position were roughly reproduced by numerical calculations using the drag coefficient obtained from the measurements.
